ELECTRICAL SYNCHRQNOUS MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 286,277, dated October 9, 1883.

(N0 model.)

To (Ml/1 whom, it may concern:

Be it known that l, PATRKCK 13. DELANY, ot' the city, county, and State of New York, haveinvented certain new and useful Improvements in Synchronous Movements, of which the following is a specification.

The object of my invention is to provide means by which electricallyconnected apparatus can be caused to move simultaneously in the same time. Under the organization whiclrl will 110w describe, momentary variations within certain limits, either of acceleration or of retardation, are promptly corrected by retarding or accelerating electrical impulses; and such variations, being constantly corrected whenever they occur, do not constitute imperl'cctions in the operation ofmy invention. Various devices have heretofore been employed for governing such movements, and among others tuned forks and other vibrators; and in several applications for Letters Patent filed simultaneously herewith, I have described and illustrated systems of operation in which electrically-controlled vibrators are relied upon to maintain the synchronous movement of the diflcrent apparatus. Under the organization herein disclosed, however, I dispense with the use of vibrators of any description, and employ a continuously-acting, non-vibratory, automatic circuit-brcaker, in the interrupted circuitof which the motor-magnet which drives the electrically driven orrotated apparatus at the different stations is placed.

in the accompanying drawings, Figure 1 is a plan view, partly broken away, illustrating the transmission-instrument; Fig. 2, a side elevation of the same with the contact-tongues broken oii. 'Fi g. 3 is a diagrammatic plan view illustrating two stations connected by a main line, and Fig. i is a similar view of a slightlymodi'tied organization.

Referring to Figs. 1 and 2, the apparatus is mounted upon a base-board, A, in which a vertical rotating shaft, 13, has its lower bearing, the upper bearing of the shaft being in the-bridge piece or strap 13. A stationary table, 0, on the face of which a series of insulated contacts is arranged, is placed concentrically around the rotatingshal't D, and a trailing finger or circuit-completcr, 0, held ad- 'justably in the outer end of a radial arm, I),

projecting from the insulated hub on the retating shaft, sweeps over the table of contacts. A spring contact-tongue, a, mounted in a suitable post or support, a, bears upon the hub a, and is electrically connected with the main line.. As the trailing finger therefore moves over the circular table of contacts, the main line will, through the tongue a and trailing finger c, be successively momentarily placed in communication with each of the insulated contacts on the stationary table. Just above the hub a is an armature-disk, D, fast on the vertical shaft B. This disk is provided with arn'lature-teeth d on its periphery, which revolve in close proximity to the poles of the magnets E E and F F, as is presently described. On the upper face of the armature- (lisk D is a cylindrical case, (1, filled with mercury to render the motion of the disk uniform. A make-and-break wheel or circuit-interrupt er, is secured on the vertical rotating shalt B, just above the cylindrical mercury-ease d. A spring contact-tongue, 1 bears upon the periphery of this wheel, and the electrical connection is alternately broken and completed through the wheel, the hub 7', and the sprii g contactfinger g, which bears upon the hub. The spring '5 is electrically connected with one end of a local battery-circuit, in which the motor-magnet F F, which actuates the rotary disk D, is placed, and the contact-tongue g is connected with the other end of the circuit. In order to prevent sparks between the breakwheel and the tongue i, a shunt containing a resistance, R, is thrown around them, as in Fig. 8. An impulse of ro tation having been inr parted to the vertical shaft, the local or motor circuit will be automatically made and broken through the break-wheel g, and the magnet F F magnetized and demagnetized; and when the speed of rotation corresponds with the makes and breaks in the circuit, the arma ture-teeth (I will be alternately attracted and released by the poles of the motor-magnet F F, and the disk continuously rotated, as is well understood. This magnet is mounted upon a sliding support or standard, F, which is adjusted to and from the teeth dot the armature-disk by means of a suitable screw, 1. The magnet E E is for the purpose of regulating the speed of rotation, and acts upon I GO the armature-teeth cl whenever correcting im- I is made to rotate, as it readily may be, two or pulses of electricity are transmitted over the line, as hereinafter described. This magnet is mounted upon a sliding support, E, which is adjusted toward and from the armatureteeth (I by means of a thumb-screw, e, mounted in a vertical ear or bracket on the base-piece E This base-piece is adjustable on the bedpiece A of the instrument by means of curved slots and set-screws 0, so that it may be adjusted sidewise concentrically with the arma-' ture-disk D. By this adjustment the poles of the magnets E can be brought into the proper relation to the teeth on the rotating armaturedisk, so that the correcting impulses of electricity will act properly upon the teeth of the rotating armature-diskto regulate its movement, as hereinalter described.

In Figs. 3 and 4 the parts are, for the purposes of illustration, represented diagrammatically, and the stationary table of contacts is shown as placed above the rotating armature-disk and interposed between that disk and the trailing finger c.

The device of employing a mercury-case for evening the speed of rotation of the armaturedisk is not new with me, and forms no part of the present invention; nor is it necessary to the operation of my invention, though I prefer to employ it. The manner of driving the armature-disk-that is, by means of a motormagnet placed in a circuit which is automatically made and brokenis alsov old, as is well understood. I11 organizations, however, like those herein illustrated, the motor-circuit has been made and broken by the action of an automatic vibrator, and not by means of a rotary circuit-breaker, nor by a circuit-breaker operated directly by the rotation of the disk itself.

Two stations, X and Y, are illustrated in the drawings, and at each station I have shown a table of contacts on which sixty insulated contacts are placed. These contacts are divided into groups or series of ten each, making six groups, and two of the contacts in each group those numbered 9 and 10are devoted to maintaining the synchronous movement of the ap-' paratus, as will be described. The remaining eight contacts in each series maybe connected in any desired Way with electrical apparatus at each of the stations. i

It will be obvious that if the trailing fingers 0 rest on corresponding contacts at the two stations the circuit between them will'be complete. Any apparatus, therefore, connectedin proper electric circuit with such corresponding contacts at each station will receive an electrical impulse once for each revolution of the trailing finger. If several instruments at each stationsay fourare connected up in. independent circuit with two of the contacts of each of the six series, it will be obvious that. the circuit over the main line will be completed through the corresponding instruments at each station twelve times in each revolution of the trailing fingers. If the apparatus three times per second, each set of instruments will be plactd in communication with the line twenty-four orthirty-six times in every second, and the circuit will be practically unbroken. The line may therefore be used either for the transmission of messages telegraphically or for any other purpose to which such an arrangement is applicable.

The speed of rotation of the apparatus is regulated by adjusting the motor-magnet F to or from the armature-disk. The closer themagnet is brought the more powerful is its action on the disk and the higher the speed of rotation. Thirty breaks are shown in the circuitbreaking wheel and thirty teeth on the armature-disk, and the break-wheel is of course so fixed relatively to the teeth that the magnetizing and demagnetizing of the magnet are timed to attract and release the teeth at the proper moment and maintain its continuous rotation.

In order to insure the synchronous move ment of the apparatus at the two stations, I make use of the following arrangement: At station X three of the 9s, most widely sepa rated from each other are connected together and tea correcting-battery, O B. The other three intermediate 9s are thrown out or unconnected. At the other station, Y, the 9s corresponding with those connected with the battery 0 B at station X are thrown out, and the-other 9s corresponding with those unconnected at station X are connected with the correcting-battery O B. At station X three 10s most widely separated are connected to each other and to a line which passes through the coils E E of the regulating or correcting magnet to the ground, while the remaining alternate 10s are unconnected. arrangement is, again reversed, those 10s cor responding with the unconnected 10s at station X being connected together. and to a line which passes through the coils E E of the regulating-magnets, while the lOs corresponding with the connected 10s at station X are thrown out. At both stations it will be observed that the connected 10s are built out or extended toward the adjoining 9s.

As described in connection with Figs. 1 and 2, the magnet E E can be adjusted both to and from the teeth of the armature-disk and sidewise concentrically therewith, to act in conjunction with the motor-magnet to increase the speed of rotation of the disk.

WVhen the trailing finger or circuit-completelat station X is on a battery-connected 9, if'the tongue at Y happens to be running a trifle faster and touches the edge of an extended 10 at that station, a current of electricity will be received from the battery 0 B at station X through the 9-contact and trailing finger at that station over the main line, trailing finger, and l0-contact at station Y through the coils 'of the correcting-magnet E E. Each correcting-magnet, when adjusted for retarding, is placed relatively to the magnet F and armature-teeth,

At station Y the IIO acme a as shown in the drawings that is, when two I armatureteeth are directly opposite the poles of the motor-magnet F and the motor-circuit is just being broken, as appears from the circuit-breaking wheel, two teeth on the opposite side of the disk have almost passed from in front of the poles of the correcting-magnet E. If, therefore, the correcting-magnet is en ergized at this moment, it will momentarily attract the teeth just passing from its poles and retard the speed of rotation. \Vhen the magnet F is energized and is attracting the two teeth approaching its poles, two opposite teeth come in front of the poles of the correcting magnet and a correcting-impulse is received. That magnet will momentarily tend to hold these teeth and retard the rotation. The operation is exactly the same at the other station.

As the local motor-circuit at both stations is broken by the break-wheel the same number of times in a single revolution of the trailing fingers with an approximately equal batterypower, the apparatus at the two stations will revolve at* about the same speed, and when once brought into synchronism their continuous uniform rotation is automatically maintained by the reciprocal correctingimpulses of electricity transmitted from both stations, according as the apparatus at one station runs faster than that at the other. By shifting the magnet E they may of course be arranged to operate in conjunction with the motor-magnets to accelerate the speed when an electrical impulse is received. The correcting 9 and 10 contacts must, however, be arranged for acceleration. This can readily be done by reversing their relative battery and correctingmagnet connections and extending the 9s toward the 10s, instead of the 10s toward the 9s.

The specific arrangement of the correcting 9's and 10s at each station forms the subject matter of another application filed simultaneously herewith, numbered 91,489.

As above remarked, in several applications for patents riled simultaneously herewith, and respectively numbered 91,490 and 91,491, I have shown other arrangements of contacts for automatically correcting the motion of rotary apparatus controlled by an automatic vibrator. Obviously, the non-vibratory circuit-breaking apparatus herein set forth may be used in connection with the systems of operation set forth in those applications.

In Fig. 2 an organization is shown like that in Fig. 1, except that, instead of employing a separate magnet for the retarding or accelerating correctingimpulses, the correcting-coils E are mounted upon the same cores as the motor-coils F, so that the effect of correcting electrical impulses which prolong the magnetism of those cores is to hold the armature-teeth in front of them and retard the rotation of the arm aturedisk.

The right to hereafter file other applications for any subj cot-matter herein shown or de scribed and not fully claimed is reserved.

Any subjects-matter herein shown or de scribed, but claimed in cases 91,488, 91,489, 91,490, 91,491, or 91,493, filed. of even date herewith, or No. 102,928, filed August 6, 1883, are disclaimed herein.
